For example, 360-degree video data can be obtained for processing by an encoding device or a decoding device. The 360-degree video data includes pictures divided into motion-constrained tiles. The 360-degree video data can be used to generate a media file including a plurality of tracks. Each of the plurality of tracks contain a set of at least one of the motion-constrained tiles. The set of at least one of the motion-constrained tiles corresponds to at least one of a plurality of viewports of the 360-degree video data. A first tile representation can be generated for the media file. The first tile representation encapsulates a first track of the plurality of tracks, and the first track includes a first set of at least one of the motion-constrained tiles at a first tile location in the pictures of the 360-degree video data. The first set of at least one of the motion-constrained tiles corresponds to a viewport of the 360-degree video data.
